摘　　要：通过对大量的文献资料进行归纳分析,综述了泡佩克斯图在应用中存在的问题,确定了该图的应用条件、范围及注意事项,扩展了泡佩克斯图的使用范围;得出了lewis酸碱对的电势-pH图;基于同时平衡原理成功解决了金属-配位体-水系中电势-pH图的计算问题;形成了高温下的M-H2O体系的泡佩克斯图,为科学研究和工程技术人员提供了更为详实的可查阅资料,最后展望了泡佩克斯图的研究前景和潜在的应用价值。Through abundant data analysis, problems in application of Pourbaix map are reviewed. Conditions, field and precautions for using the map are determined, which extend the using field. Lewis Acid-base Pair of potential -pH map is obtained. Based on simultaneous equilibrium principle, the calculating problems of -pH map in metal-ligand-water systems are successfully solved, and Pourbaix map of M-H2O system under high temperature is constructed, which provide data accessible to scientists and engineers. The prospect and application value of Pourbaix map is studied.
